Thanks, Bruce. I've sent an email to him. He mentions Gwet in his acknowledgments, so it'll be interesting what Gwet says about all of this.

Hi Brian. The author of kappaetc can be reached via the e-mail address at
the bottom of that text file I uploaded. You could always ask him directly
what method(s) he used.
Cheers,
Bruce
